BRAKE-BEAM SUPPORT.

Application filed May 15, 1922. Serial No. 718,487.

To ,aZZw/wm it may concern:

Be it known that I, BRODERICR iiiasnnnr, residing at Franklin, in thecounty of Venango and State of Pennsylvania, a citizen of the UnitedStates, have invented or discovered certain new and'useful Improvementsin Brake-Beam Supports, of which improvements the following is aspecification.

The invention described herein relates to certain improvements in themanner of securing to a truck element, rails adapted to serve assupports for brake beams, said rails being supplen'ientary to the usualhangers and more particularly to improvements on the constructiondescribed and claimed in the application filed May 15, 1924, Serial Number 713,488. The invention is hereinafter more fully described andclaimed. I In the accompanying drawings "forming a part of thisspecification, Fig. i is a view partly in section and partly inelevation, showing brake beams supporting rails secured to the springplank of a truck; Fig. 2 is a plan view 01 the construction shown inFig. 1; Figs. 3 and at are views similar to Fig. lyillustratingmodifications of the manner of attaching the rails to the spring plank;Fig. 5 is a plan view of the construction shown inFig. i; Fig. 6 is adetail view of the locking key employed in the construction shown inFigs. 4 and 5; and Fig. 7 is a view similar to Fig. l of a -furthermodification of the improvement claimed herein. I

In the practice of the invention the supporting rails I extend inopposite directions from a truck element, as the spring plank 2,sutliciently far to underlie elements of brake beams, as for example,the tension member 3 of a truss brake beam. As is well known to thoseskilled in the art, the brake shoe, when carried by beams supportedsolely by the usual hanger, will not bear concentrically on the wheels,and hence in order to ensure the proper application of the shoes on thewheels, the portions of the supplementary supporting rails along whichthe tension member will reciprocate, are upwardly inclined as shown at4b, to so support the brake beam that the curved faces of the shoes willbe at all times concentric, or approximately so, with the treads of thewheels.

In order to attach the rails to the spring plank, holes 5 are formedtherethrough at points adjacent to the flanges 6 along the edges of theplank to permit or" the insertion of toes 7 on the inner ends of therails. in forming the toes the ends of the rails are so bent as to formshoulders or abutments 8 in such relation to the toes that when thelatter has been placed in position and bears on the underside of theplank 2, the shoulders 8 will bear against the inner side of the holes 5and prevent any inward movement of the rails. Outward movements of therails are prevented by shoulders or abutments 9 so located on the railsas to bear against the inner faces of the flanges 6 when the rails havebeenplaced in operative position.

lVhen the spring plank is formed of channel bars, or angle bars havinghigh flanges, (i as shown in Fig. 8, the inclined portions at of therails extending horizontally from the upper edges of the flanges, wouldbe above the tension member 01'' the brake beam. In such cases, Ushapedbends 10 are so tor-med in the rails for the reception of the flanges 6The upper portions of the inner legs 11 of the U-shaped bend bear on theinner faces of the flanges and pre vent any material outward movementsof the rails. The outer legs 12 which extend down along the other facesof the flanges, are madeot' such lengths that the inclined portions i ofthe rails will be in proper po sitions relative to the brake beams. Itis preferred that the legs 12 should be so bent as to form fulcrums 13so that the weight oi the brake beams on the inclined portions at willhold the toes 7 in engagement with the spring plank. As the brake beammay, at times, swing upward considerable distances and permit of suchupward move ments of the outer end of the rails as to shift the lowerends of the legs 11 outward tar enough to move the toes into alinementwith the holes 5, it is preferred to prevent such movements by means 01blocks let inserted in the holes 5 outside of the shoulders 8, as shownin Fig. 3. The blocks may be so held on the leg 11 as to be slidabletherealong by any suitable means, as for example, by wings 15 on theblocks adapted to be bent around the legs 11.

In the construction shown in Figs. 4: and 5, the toes are formed by theends of hooks formed on the inner ends of the rails and the bottoms ofthe hooks forming the shoulders or abutments 8 These hooks are so formedas to engage the edges of the hole 5 formed in the Web of the springplank.

This hole is made of such a length as to permit of the insertion of thehooks sequence and said hooks are held in operative position by suitablemeans such the key 16, which consists of a plate slit for a suitabledistance from opposite ends, thereby forming tongues i? adapted to bebent over onto the rails. As it is pi "red that the portions 15' of therails adjacent to the hooks should be lat on the web of the springplank. ii-shaped bends 19 are formed for the reception of the flanges (3ol the plans as shown in Figs. Liand Z.

In lieu of the construction shown in Figs. 1 to 5 whereby the inner endsof the supportin rails are held in engagement with the wen ot the springplanle such means eon Sistine oi toes i'oruied integral. 'h thepoitions. 53 or S, of the rails projecting through the web oi the plankthe locking function of these toes may be eii'eeted by means detachablefrom the portions 8 or 8. Such an alternative construction is shown in7. the portions 8 and 8 being e:-;tended siniiciently tar beiow thespring plank :2 shown at 8" to permit of the. )assing of a l key or gib20 through the par ts below the web.

I claim herein as my invention 1. The combination oi a truck element andbrake beam supporting elements having their inner end portions arrangedabove the truck element and extending at right angle from opposite sidesof the truck element he inner ends of the rails being provided withmeans adapted to detachably engage the truck element and hold the innerend portions of the rails as against vertical movement 2-. Thecombination of the spring plank of a car truck, brake beam supportingrails having their inner end portions arranged above the truck elementand having their inner ends detachably engaging the spring plank andbearing on the spring plank at points outside of the points oiengagement of the inner ends with the plank.

3. The combination of the spring plank ot a car truck, brake beamsupporting rails provided at their inner ends with portions integralwith the rails and adapted to project through the spring plank andmaini'or preventing the withdrawal oi such p0"- tions from said springplank he combination oi the spring plank of a car truck and brake beamsupporting rails provided att-heir inner ends with portions adapted tobe passed through holes in the plank and bear on the underside thereoi,said rails bearing on the upper side of the plank at points outside oftheir attachment to the plank.

i). The combination of a flanged spring plank 01 a car truck havingholes through the web portion thereof and brake beam supporting railsprovided with toes adapted to be passed through the plank and engage theunderside thereof, and having shoulders adapted to bear on the flangesof the truck and prevent such movements of the rails as will permit thedisengagement ot' the toes from the plank.

(3. i re combination of a flanged spring plank raving holes through theweb portion thereof and brake beain supporting rails provided with toesadapted to be passed through the piank and engage the underside thereofand provided with U-shaped portions for the reception of the flanges onthe plank.

7. The combination of a flanged spring plank, brake beam supportingrails having their inner end portions arranged above the plank andprovided with portions adapted to project through the web of the plankand having shoulders adapted to bear against the inner faces of theflanges of the plank and means bearing against the underside of theplank and adapted to lock the inner ends of the rails to the plank.

in testimony whereof, I have hereunto set my hand.
